I wish people would start with a "rom format" for windows games. There's so many old games and no standardized way to run them.

You mean ISOs? ;)

I think he means where the DOS/config is all set up too. Sort of like a really small VM.

		It was a joke, because ISO is a file copy of a CD-ROM disc. ;)

You mean a packaged file that one simply runs? Isn't that the installer?

		An installer extracts and moves a bunch of files from a blob to the filesystem, writes registry values (on Windows anyway), sets environment variables, sets up services, permissions and a bunch of other things, does it not? A ROM is a binary blob that some executable accepts as input and interprets, the executable being the emulator, which simulates the target hardware well enough that the ROM's machine code runs as if it were on the original silicon.

ScummVM has effectively done this.
